Abstract
The utility model relates to a dual-layer membrane structure for a membrane pump, in particular to a dual-layer membrane structure with a guide rod for a membrane pump. The dual-layer membrane structure with the guide rod for the membrane pump comprises a dual-layer membrane, a pressure plate and the guide rod; the dual-layer membrane comprises an oil side membrane and a medium side membrane; a membrane liner communicated with the oil side membrane is arranged in the middle in the medium side membrane; a connection hole is formed in one side, close to the oil side membrane, on the membrane liner; the position, corresponding to the connection hole, of the pressure plate is fixed on the oil side membrane; one end of the guide rod penetrates through the pressure plate to be fixed in the connection hole. The dual-layer membrane structure with the guide rod for the membrane pump has the beneficial effect of solving the problem that the structural stability is damaged as the pressure plate at the medium membrane side is corroded in the prior art is solved.
Description
Technical field
The utility model relates to the double-deck membrane configuration of a kind of diaphragm pump, particularly relates to the double-deck membrane configuration with guide rod for a kind of diaphragm pump.
Background technique
Double-deck barrier film for traditional diaphragm pump (double-deck barrier film comprises oily side barrier film and side medium barrier film) structure mostly is flat board, bowl type or corrugated structure, can only realize the automatic makeup functional oil of hydraulic pressure cavity, can realize the automatic makeup of hydraulic pressure cavity, the membrane configuration of oil extraction function is generally the single-layer septum structure with guide rod, but this structure can not realize the warning function that breaks of double-deck membrane configuration.Therefore there are forefathers to design the double-deck membrane configuration with guide rod for a kind of diaphragm pump, as shown in Figure 2, the guide rod 1 of this structure runs through double-deck barrier film, and by the pressing plate 2 of double-deck barrier film both sides, guide rod 1 is fixed, controlling barrier film by guide rod 1 moves reciprocatingly, make this structure not only realize automatic makeup, the oil extraction function of hydraulic pressure cavity, realize again the warning function that breaks, but because the medium of side medium in hydraulic pressure cavity has corrosivity, make the pressing plate 2 of this structured media side barrier film 4 sides easily be corroded and damage, and then destroy the stability of this structure.Obviously, diaphragm pump is with solving the problems referred to above with a kind of suitable structure of double-deck membrane configuration exigence of guide rod.
Summary of the invention
The purpose of this utility model is to provide the double-deck membrane configuration with guide rod for a kind of diaphragm pump, is corroded and destroys the problem of structure stability to solve the pressing plate because of side medium barrier film side existing in prior art.
The purpose of this utility model can reach by following technical measures,, double-deck membrane configuration with guide rod for this diaphragm pump, comprise double-deck barrier film, pressing plate and guide rod, described double-deck barrier film comprises oily side barrier film and side medium barrier film, and in side medium barrier film, middle part is provided with the barrier film liner that is communicated with oily side barrier film, is lining with, is provided with and connects hole near a side of oily side barrier film in barrier film, the position that pressing plate correspondence connects hole is fixed on oily side barrier film, and one end of guide rod is run through pressing plate and is fixed on and connects in hole.
Further, described in, connecing hole is tapped hole.
Further, described barrier film liner is convex metal inner lining.
Further, described guide rod end is provided with interior threaded hole, and to being provided with screw column by interior threaded hole, screw column runs through pressing plate and connects hole and be fixed together.
Further, on described pressing plate, corresponding screw column is provided with tapped hole.
Further, described screw column and pressing plate junction are circumferentially with seal ring.
Compare the double-deck membrane configuration with guide rod for traditional diaphragm pump, the utility model diaphragm pump is by the advantage of the double-deck membrane configuration with guide rod: 1, because the utility model diaphragm pump is provided with middle part in side medium barrier film described in the double-deck membrane configuration with guide rod the barrier film liner that is communicated with oily side barrier film, in barrier film, be lining with, oil side diaphragm end is provided with and connects hole, the position that pressing plate correspondence connects hole is fixed on oily side barrier film, guide rod runs through pressing plate and connects hole and be fixed together, guide rod is fixed without running through double-deck barrier film, so needn't pressing plate be set in side medium barrier film side, and then the pressing plate of having avoided side medium barrier film side is corroded and destroys the stability of structure, 2, because the utility model diaphragm pump is provided with interior threaded hole with guide rod end described in the double-deck membrane configuration with guide rod, to being provided with screw column by interior threaded hole, screw column runs through pressing plate and connects hole and be fixed together, and on pressing plate, corresponding screw column is provided with tapped hole, coordinate guide rod and barrier film are fixed together with pressing plate by screw column, both guaranteed that barrier film was not compressed by transition, guaranteed again the sealability between barrier film and guide rod.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the utility model diaphragm pump with the double-deck membrane configuration with guide rod;
Fig. 2 is the structure sectional view of existing diaphragm pump with the double-deck membrane configuration with guide rod;
